T-Mobile announced a new unlimited data plan today that includes unlimited data, text, and calls for $70 a month for the first line, $50 for an additional line on a family plan, and $20 for lines after that. Unfortunately, “unlimited” is a misnomer.

The new plan, called T-Mobile ONE, comes with two caveats. First, video is limited to standard definition and will stream at a maximum of 480p. If you want HD video, you need to shell out an additional $25 a month. This is a lot like T-Mobile’s misunderstood Binge On service, which cuts video quality in favor of offering “unlimited” access to a number of video services.

The new plan also throttles your internet speed when tethering. While you can still tether to your phone, it’s capped at 2G speeds, which is useless for pretty much everything. For LTE speed, you need to pay an additional $15 a month for 5G of data. Also, just like their previous unlimited plans, if you fall into the top 3% of data users, which usually means you’re using around 26GB a month, T-Mobile throttles your speeds. T-Mobile ONE will be available on September 6th. For now, the Simple Choice plans are still available.
